. to a casing-section which is adapted to form a part of a book-formsafe.

It may be stated preliminarily that a savin s bank of the character herereferred to is rnown as a library-safe, and comprises a casing-sectionwhich corresponds with one side, the back, and the edges of a book, anda closure which corresponds with theother side of a book.

The present machine is adapted to pre liminarily form the cover about asheet metal member which is adapted to form one side and the back of thecasing of the safe and to removably secure the sheet-metal member andthe partiall folded cover to a removable die or holder.

This work is preliminary to lurther operations in another machine, intowhich the dieor holder, the attached sheet-metal member of the casing,and the cover may be in-- troduced, The primary object of the presentinvention is to provide simple and easily operated mechanismforperforming the preliminary operation referred to.

The invention is illustrated, in its preferred embodiment, in theaccompanying drawings, in which Fig. 1 represents a side elevationalview of a press embodying the invention, the die or holder beingremoved, and the-handle of the actuating lever of the plunger beingbroken away; Fig, 2, a plan view of the machine; the dotted linesindicating the position of the cover mentioned; Fig. 3, a brokenperspective view, showing the die or holder inposition in the bed of themachine and showing a cover for a book-form safe properly positioned onthe bed and extending across the die; Fig. 4,21 broken perspec-' tiveView illustrating the prelimlnary folding of the cover about thecasing-section, the

plunger being in the position which occupies while forcing thecasing-section into the die and thus folding the cover about thatportion of the casing-section which corresponds with the back of thebook-form safe;

Fig. 5, a broken-perspective view illustratng the manner in which theback of the casing-section and the folded cover are secured to the die;Fig. 6, a perspective view of the holder or die employed; Fig. 7, alongitudinalsectional view of the die, the dotted lines indicating theposition of thecasing-section; and Fig. 8, a transverse vertical sectionshowing the plunger forcing the casing-sec-.

tion into the die and effecting the folding of the'flover about the backportion'of the casing-section.

In the construction illustrated, A represents the bed of a press whichis provided w th a transverse slot or socket A for recelving adle, thebed of the press being further provided on its upper side withtransverse ledges or gage members A and A and being also provided withlateral gage members A, these gage members being adapted. to position aflexible cover, which may be of leather or artificial leather, upon thebed-plate; B, standard which rises from the rear portion of the bed; andhas a forwardly-curved arm equipped with a. guide B for the plunger C, aplunger working in said guide, said plunger being provided at its lowerend with a transverse header bar C; and D, a lever mounted on thestandard B andserving to actuate the plunger.

Removably mounted in the transverse slot or socket A of the bed of thepress is a die or holder A This holder is shown in perspective in Fig.6. It is adapted to be transferred to another press and to be mounted indifferent positions in such press to enable the binding operations to becompleted. However, in the present press, the holder A is entered onlyin the position shown in Fig. 3, that is, in such position that itsconcave side will be turned upwardly and in position I form edge memberwhich is of angle-form cross-section, this edge member,(not shown)corresponding with the edges of the leaves of a book. In completingthestructure of the device, the U-shape member of angleformcross-section has one flange turned inwardly and provided withperforations which receive the clenching lugs 1 The cover for thecasing, which may be of leather, artificial leather, or other suitablefabric, is designated 2. It has its corners cut away and provided withcorner-tabs 2, as shown in Fig. 3. The marginal portions of the coverare provided with perforations or recesses 2 which are adapted toreceive or engage the brads or clenching lugs 1 of the casing-section,after such margins have been folded over the edges of the sheet-metalmember.

The die or holder A comprises a metal bar 3 which has its upper sideprovided with a longitudinal concavity 3 which is adapt ed to receivethe rounded back 1 of the casing-section; and a pair of clamping-slides4 movable in longitudinal guides 5 with which the bar is equipped at itsends. The clamping-slides 4: have their inner ends made concave-convexin cross-section, thus providing comparativey sharp curved edges 5 whichare adapted to fold the central portions of the projecting margins ofthe cover designated 2 (see Fig. 4.) inwardly over the inner surfaces ofthe end portions of the curved back 1*, it being understood that thematerial is first preliminarily tucked in by the operator, and that theslides 4 are then shoved inwardly to complete the folding operation andclamp the casing-section and the cover to the die or holder A as shownin Fig. 5. The slides 4 are equipped near their inner ends with studs 4*for limiting the outward movement of the slides and are equipped attheir outer ends with thumb pieces 4* by means of which the slides maybe actuated. It will be noted from Fig. 7 that the bottom of the recess3 is slightly below the plane of the bottoms of the slides 5*, so thatthe slides can move over the metal of the casing-back and the infoldedtucks 2.

The bar 3 is equipped at one side near its ends with blocks 3 which areadapted to engage the lateral edges of the bed-plate A when theholder ordie is in position, as shown in 'Fig. 8. These blocks are shown equippedwith studs 3, which serve a function, when the holder A is employed inthe other machine referred to, but which possesses no function in thepresent machinehe bed-plate A is equipped at its lateral edges withstuds 6, the function of which is to prevent the die or holder A frombeing entered improperly in the socket A.

The operative-portion or transversely elongated head C of the plunger isprovided at its front side with vertical slots 7 which are so positionedas to accommodate the clenching lugs 1 when the plunger movesdownwardly, so as to engage the inner surface of the back portion 1 ofthe casingbe forced into the recess 3 of the die or holder 31 while theplate 1 occupies a standing position in front of the plunger. Thecover-section may be centered by causing the lugs 1 to register with theslots 7 of the plunger. The operator then depresses the plunger and thusforces the back-portion of the casing-section into the groove 3 of thedie, thus folding the cover about the back l While the plunger is heldin depressed position, the operator folds the tucks 2 in-.

wardly over the inner surfaces of the backportion 1" and moves theslides 4 inwardly, thus clamping the back-portion of the casingsectionand the intermediate portion of the cover to the die or holder. Theplunger is then retracted and the holder is taken from the press andtransferred to another machine,

which is capable of performing further operations and completing theconstruction of the safe.

The other machine referred to forms the subject-matter of my copendingapplication No. 467,703, filed in the United States Patent ()ffice ofeven date herewith.

From the description given, it will be understood that the presentinvention embodies means for expeditiously forming a cover about theback portion of a casingsection and clamping the casing-section andcover to a holder or die which is capable of being used in another pressfor completing the construction of the safe.
